• The most common complication resulting from Ascaris infestation is obstruction of the small intestine. While medical treatment can usually prevent serious complications, complete intestinal obstruction by this helminth can result in death. Because of the dangers of perforation, volvulus, and strangulation and the increasing toxic effects of ascariasis, the surgeon should not temporize unduly when medical treatment is, or seems likely to be, ineffective. physical and x-ray findings, and especially one's over-all judgment, should contribute to the decision to intervene surgically, and gross operative findings should determine further surgical procedures.
